Claims.

This invention relates to plows.

An object of the invention is the provision of a one-way disc plow which is provided with a rigid hitch bar directly attached to the draw bar of a 5 tractor so that the plow will fall directly in the path of the tractor thereby eliminating slipping on hillside plowing.

Another object of the invention is the provision of a one-way disc plow which is rigidly connected to the draw bar of a tractor and which is provided with an eccentric mechanism for'raising and lowering the plow to provide variations in the depth of the plowing, the plow being supported by wheels having relatively wide rims which will insure the proper position of the plow and penetration.

A further object of the invention is the provision of a one-way disc plow which is adapted to be rigidly connected to the draw bar of a tractor and which has a rigid one-piece straight line frame which is supported by wheels at its opposite ends with plows connected to the frame in staggered relation, the beam of the frame being disposed at an angle to the line of travel of the plow.

This invention will be best understood from a consideration of the following detailed description, in view of the accompanying drawing forming a part of the specification; nevertheless, it is to be understood that the invention is not confined to the disclosure, being susceptible of such changes and modifications as define no material departure from the salient features of the invention as expressed in the appended claims.

In the drawing:

Figure 1 is a plan view of a plow constructed in accordance with the principles of my invention,

Figure 2 is a side view of the plow shown in Figure l, and

Figure 3 is a vertical section taken along the 40 line 3-3 of Figure 2. 1 a 7 Referring more particularly to the drawing l0 designates a longitudinal beam which is composed of a long section II and a short section l2. The longer section II is inclined at a slight angle 5 to the line of travel of the plow while the shorter section l2 extends at an angle from the rear end of the section II. The short section I3 of the beam extends rearwardly and is disposed at approximately right angles to the section l2.

A hitch bar is connected at 2| to an intermediate portion of the longer section I I of the beam Ill. The bar is twisted at 22 to provide a horizontal portion 23 which is adapted to be rigidly connected at 24 with a draw bar 25 of a tractor (not shown).

A transverse beam is connected at 3| to an intermediate portion of the hitch bar 20 and extends approximately at a right angle from the hitch bar andis connected with'the front end of the beam H] as shown at 32. The beam ill is con- 6 nected to an intermediate portion of the beam 33.

A brace bar is connected at 36 in any approved manner with the forward end 23 of the hitch bar 20. The other end of the bar 35 is. connected to a plate 31 which is welded to the outer 10 end of the transverse beam 30.

A crank plate 49 is pivotally mounted on a bolt ll which is supported by the plate 31. A wheel 42 of considerable width is rotatably' mounted on an axle 53 which is carried by the lower end ofthe plate 40.

A lever-45 is rigidly secured at 46 to the upper end of the .plate and above its pivot 4|. This lever is provided with a pawl 41 which engages teeth 48 of an arcuately-shaped rack 49 which is 20 secured at some the plate 31. The pawl 47 is of the usual type and is designed to be released from engagement with teeth 43 against the tension of the spring and in a manner which will be presently described. Thelever is adapted to rock .25 the crank plate 40 for raising the axle 43 of the wheel 42 with respect to the beam III, while the pawl 41 holds the lever and crank plate in position.

A reinforcing plate 56 is welded to the top of 30 the beam IE but at 5| this plate is turned at an angle to the main portion of the plate so that it will extend rearwardly, as shown at 52, and in a direction which is parallel to the line of travel of the plow. The reinforcing plate is welded to '35 the top of the section ID of the beam, as shown at 53, and. terminates adjacent the rear end of the very short section l3 of the beam. The end of the section l3 and the rear end of the section 52 of the plate are secured to opposite sides of a supporting plate 54.

A crank plate 60 is pivotally mounted upon a bolt 6! which is carried by the supporting plate 54. The lower end of the crank plate is provided with an axle 62 upon which is mounted a 45 flat-faced wheel 63 which has even greater width than the wheel 42.

V A lever 65 is rigidly connected at 66, with the crank plate 6!) and is provided with a pawltl slidably mounted in a bearing 68 against the tension of a spring 69 and has its free end engageable between the teeth IQ of the arcuatelyshaped rack TI. This rack isrigidly secured, as shown at 12, with the plate 54. A coil spring 5 is adapted to maintain the lever 65 in its rearward position.

A hand lever 15, pivoted at H on the lever 65,

has an arm 13 which is connected by a rod or wire 19 with the top of the pawl 61 so that when the lever 76 is rocked the pawl will be released from engagement between the teeth of the rack I I.

The lever 45, the pawl 41 and the related construction, are identical with that of the lever 65, the pawl 67 and its related construction.

An arm 80 is welded at 8| to a side wall of the beam Ill and is extended laterally and slightly rearwardly. An axle 82 is carried in bearings 83 and is bolted at 84 to the outer free end of the arm 80. A coulter plow 85 is rotatably mounted on the axle 82 and is located just behind the plate at the front end of the plow.

A brace bar 85 connects the outer end of the arm 80 with the side wall of the beam in.

An arm 90 extends laterally from the beam I0 at the rear of the'arm 80 and supports bearings 9| at its free end for an axle 92 of a coulter or plow 93. A brace bar 94 connects the outer, end of the arm 90 witha side wall of 'the beam l0.

Bearings 95 secured to the outer'end of the section l2 of the beam ID are adapted to support an axle 96 of the circular coulter or plowr9l.

The operation of my device is as follows: The outer end of the hitch bar Zll'is connected directly to the draw bar 25 of the tractor so as to swing but not move bodily relative to the tractor and whereby the plow will be guided in a direct line of travel of the tractor and thus prevent side slippage of the tractor. e

The wheels 42 and 63 are quite wide as compared to the diameter of these wheels so that these wheels will support the plow above the ground and maintain the plow level at all times and preserve the depth of the plowing or penetration after the plow has been properly set. It will be also noted .that the wheel 63 is approximately in the line of travel of the tractor while the wheel is oifset laterally whereby the plows 85, 93 and 9'! will be supported between parallel lines passing through the hitch bar 20 and the horizontal axis .of the wheel 42.

It will be noted that the disposition of the longer portion of the beam l0 provides a staggered arrangement of the plows whereby a considerable width of land is acted on. These plows are arranged at an angle so that the dirt will be drawn in the same direction and when the plow is used for cutting paths in fields it will cut a relatively wide path. r

The depth of penetration of the plows is controlled by the levers 45 and 65 by rocking said levers and maintaining said levers in adjusted position by the pawls 41 and 61;

In Figure 2 the wheels 42 and 63 maintain the frame of the plow. at the farthest height from the ground. When the pawls are released and the lever 45 is rocked rearwardly and thelever 65 is rocked forwardly the axles 43 and 62 will be moved and this will aid materially in 'conjunction'with the rigid connection between the bar 20 and the draw bar 25 for maintaining the plow at all times in the same direction of travel as the tractor.
